ollegr [7]

Answer: The statement, you've just prepared an aqueous solution is true.

Explanation:

When one or more number of substances are dissolved in a solvent like water then solution formed is called an aqueous solution.

For example, when a hot drink is made by dissolving a teaspoon of instant coffee and a teaspoon of sugar in a cup of hot water is an aqueous solution.

Here, both coffee and sugar are solute whereas hot water is the solvent.

Thus, we can conclude that the statement, you've just prepared an aqueous solution is true.

What dose buoyancy have to do with jumping?
Naddika [18.5K]
Buoyancy is a condition in which a physical body's average density is equal to the density of the fluid in which it is immersed.

The buoyancy offsets the force of gravity that would otherwise cause the object to sink (if the body's density is greater than the density of the fluid in which it is immersed) or rise (if it's less). An object that has neutral buoyancy will neither sink nor rise. 

Hope this helps! xx

0.60 atm of SO3 and 0.30 atm of SO2are placed in a container and the system is allowed to reach equilibrium. Calculate the press
frozen [14]

Complete Question

The complete question is shown on the first uploaded image

Answer:

The pressure is [O_2] =  4.8 *10^{-5} \ atm

Explanation:

From the question we are told that

     The  pressure of  SO_3 is  [SO_3 ] =  0.63 \ atm

     The  pressure of  SO_2 is  [SO_ 2]  =  0.30 \ atm

      The equilibrium constant is K_p  =  1.2 *10^{-5}

     The  reaction is

           2SO_3 _{(g)} ⇔ 2SO_2_{(g)} +  O_2 _{(g)}

Generally the equilibrium constant is mathematically represented as

           K_p  =  \frac{(SO_2)^2 *  (O_2)}{(SO_3)^2}

=>         [O_2] =  \frac{k_p * [SO_3] ^2 }{[SO_2]^2}

substituting values

            [O_2] =  \frac{1.2 *10^{-5} * 0.60 ^2 }{0.30^2}

             [O_2] =  4.8 *10^{-5} \ atm
